What is the historical significance of the work (its technological, scientific, or social importance)?

The major historic significance concerning the birth and growth of Japanese primary and secondary battery industries is briefed item for item in what follows.

1. Historic Background before Birth of Japanese Battery Industry

Since the first electrochemical battery was invented by Alessandro Volta in 1799 in Italy [1], a variety of batteries were developed, such as Daniell battery in 1836, Poggendorff battery in 1842, Grove battery in 1844, etc., all of which were ‘wet batteries’. Up to that point, all existing batteries would be permanently drained when all their chemical reactions were spent [2].
In 1859 Gaston Planté invented a lead-acid battery, which could be recharged by passing a reverse current through it. This Planté battery was the first-ever rechargeable battery, which is regarded as the origin of the secondary battery industry [2].

On the other hand, in 1866 George Leclanche invented a battery which consisted of a zinc anode and a manganese dioxide cathode wrapped in a porous material. This Leclanche battery achieved very quick success in telegraphy, signalling and electric bell work, which laid the base of manufacturing the ‘dry battery’. In fact, on the basis of this battery, Carl Gassner invented in 1887 the world’s first commercially successful dry battery, which became the prototype for the primary battery industry [2,3].

2. Birth and Growth of Primary Battery Industry in Japan

2.1 Birth of Japanese Dry Battery Industry

It is written in the Yai’s brochure that in 1885 Sakizo Yai invented a dry battery and also established ‘Yai Dry Battery Limited Partnership Company’, where the documentary evidence for the year of either Yai’s battery invention or his company establishment can not be accurately identified [4]. However, there is the historical evidence that in 1893 Yai acquired a Japanese patent (No. 2,086) for the dry battery invention, and that the Yai battery was installed in the seismograph (assembled by Imperial University of Science, presently University of Tokyo), which was exhibited in EXPO 1893 in Chicago, commanding strong attention from visitors [4].

Although Yai invented a battery-powered clock in 1885, for which he acquired a Japanese patent (No. 1205) in 1891, the battery used in this clock was a wet one with the disadvantage of being unusable when they froze in the winter. Hence he began his quest to manufacture a dry battery, when there was a great difficulty that chemicals were leaking out of the positive terminal, and the metal became corroded and unusable. Yai tried desperately to impregnate paraffin in a carbon rod, until he succeeded in the impregnation, resulting in the first dry battery invention in Japan, which was patented in 1893 [4].

At that time, however, ordinary households could not yet enjoy the benefit of electricity even in Tokyo, where candles and oil lamps were still used for light source, and accordingly battery-powered products were so few that the demand for batteries was very little. Under such circumstances, the Sino-Japanese War broke out in August 1894, when the Leclanche battery was the latest commercially available one in Japan, which was, however, in danger of freezing in the Manchuria’s harsh winter cold. Hence the Yai battery was boldly attempted to be used for telegraphy in the War, resulting in substantial success. Soon after, an extra edition of newspaper reported the success achieved by the Yai battery in the Manchuria’s cold, which revealed the existence of the Yai battery, and subsequently made Yai’s company grow steadily [4,5].

Specifically, Yai established in 1910 the sales division of his company in Kanda-ku, Tokyo, and then built a factory in Asakusa-ku, Tokyo, which grew to the largest in Japan with the annual production volume of more than 200,000 units as of 1921. Unfortunately, however, in September 1923 the Great Kanto Earthquake of magnitude 7.9 struck the Kanto Plane, by which all facilities of his company were burnt to ashes. Nevertheless, Yai soon managed to rebuild a new factory in Kawasaki near Tokyo (see Fig. 1), where numbers of commercially successful batteries were produced, as shown in Fig. 2 [4].

Thus Yai paved the way for the dry battery business. In fact, the functional qualities of Yai batteries were evaluated officially as the best in terms of discharge and lifetime characteristics [4]. Yai’s company beat out domestic and foreign competitors, and grew to reign supreme over the Japanese dry battery market. Eventually, he became known as the "king of dry battery" [4,5], but unfortunately he passed away by stomach cancer in 1927. Since Yai’s company was not inherited by his successors, the company name disappeared from the registry of the Japan Battery and Appliance Industries Association (JBAA) in 1950 [4,5].

2.2 Primary Batteries for Consumer Electronics

Following Yai’s glorious triumph, numbers of start-ups were established for producing dry batteries, among which ‘Matsushita Electric Co., Ltd.’ founded by Konosuke Matsushita in Osaka in 1918, achieved quantum leaps in the dry battery business by making a stepping-stone of the battery-powered lamp, as shown in Fig. 3, developed in 1923 dedicatedly for use in bicycles [4]. With great success in battery business, ‘Matsushita Electric’ was reconstructed in 1935 as a household appliance company, named ‘Matsushita Electric Industrial Co. Ltd.’, operating ‘Matsushita Battery Industry Co., Ltd.’ and ‘National Storage Battery Co., Ltd.’ as subsidiaries, both of which achieved dramatic progress after World War II by developing a great variety of primary and secondary batteries, respectively.

In fact, ‘Matsushita Battery Industry’ released in quick succession a great number of carbon-zinc (or manganese), silver-oxide, alkaline-manganese, and lithium batteries in the mid 1950’s through the early 1970’s (for example, see Figs. 4, 5, and 6), with which a huge market of consumer electronics was created in Japan [6], where it should be noticed that
(a) ‘Hi-Top’ improved dramatically the life length and temperature property of ‘Hyper’, while ‘Neo Hi-Top’ attained 17 countries’ patents and 943 domestic patents and utility model rights, and furthermore, a series of carbon-zinc batteries of Fig. 4 contributed primarily to opening up a whole new market of home appliances, with the greatest market share of dry batteries in Japan,
(b) alkaline-manganese batteries of Fig. 5 cultivated new fields of household appliances, such as tape-recorders, 8-mm movie cameras, strobes, shavers, etc., due to strong-load and low-temperature characteristics,
(c) lithium batteries of Fig. 6 released first in 1971 contributed distinctively to creating a new market of digital appliances, such as electronic watches, personal computers, digital cameras, mobile terminal devices, etc., and
(d) ‘Matsushita Electric Industrial Co. Ltd.’ together with all of its subsidiaries was merged into the today’s ‘Panasonic Corporation’ in 2008.

3. Birth and Growth of Secondary Battery Industry in Japan

3.1 Birth of Japanese Lead-Acid Battery Industry

In 1895 Genzo Shimadzu succeeded in manufacturing the first prototype lead-acid battery in Kyoto, which gave birth to the Japanese lead-acid battery industry. At that time the electric grids were so unstable that blackouts occurred very frequently all over Japan. Hence high-capacity batteries were indispensable for backup power, which were, however, dependent mostly on imports. Thereby Shimadzu took great pains to devise a high-capacity lead-acid battery, until he succeeded in developing the one of high-capacity 150Ah in 1904, which was set up for the backup power supply in his factory. However, he never dreamed that a total of 400 units of the same products of capacity 150Ah would be ordered at once from the Japanese Navy, which were utilized for telegraphy in the Battle of Tsushima in May 1905 [7].

This proven performance exemplified the industrial importance of lead-acid batteries, which further enhanced the refinement of existing manufacturing technologies. In fact, with the rapidly rising demand for lead-acid batteries for use in telephone/telegraph stations, battleships, backup power, etc., he made every effort to tool up production in his factory, until in 1912 he acquired the Japan’s first patent (No. 22,232) for manufacturing lead-acid batteries [7].

In 1917 Shimadzu established ‘Japan Storage Battery Co., Ltd.’ in Kyoto. After a continual process of trial and error, in 1919 he managed to invent an epoch-making methodology for manufacturing lead-acid batteries, called ‘reactive lead oxide production method’ [8], for which he acquired not only a Japanese patent (No. 41,728) in February 1922, but also French, English, USA, and German patents in November 1922, May 1923, May 1926, and October 1929, respectively, together with other 11 countries’ patents, including Italian, Austrian, Belgian, Czech, Swedish, Canadian, and Australian ones [7]. As a result, his factory had to have incessant visitors from home and abroad to look into the manufacturing process in operation [7]. Thus it can be seen that Shimadzu contributed outstandingly to the advance of the world’s lead-acid battery industry.

Following Shimadzu’s great achievements, Shichizaemon Yuasa started ‘Yuasa Storage Battery Co., Ltd.’ in 1918, which built the Japan’s largest battery factory in 1919 in Takatsuki, Osaka, (see Fig. 7), to meet the latent demand for lead-acid batteries, which were expected to grow after World War I (1914-1918) for use in submarines, railroad facilities, mines, telephone stations, standby power, locomotives, automobiles, etc. [9]

3.2 Motorization in Japan

With the rapid advance of Japanese motorization starting from the early 1950’s, the number of automobiles in Japan exceeded one million at the end of 1953 [7]. As the demand for automotive batteries grew at an accelerated pace, a variety of high-capacity batteries with low-temperature characteristics were newly developed in the early 1950’s (for example, see Fig. 8). In addition, with the rising demand for motorcycles, a new type of compact batteries packed in plastic containers were also produced in the mid 1950’s (for example, see Fig. 9) [7,9,10].

Thus the share of automotive batteries rapidly climbed to the top in the Japanese secondary battery market in the early 1970’s, which was achieved mainly by the big three battery companies, ‘Japan Storage Battery’, ‘Yuasa Storage Battery’, and ‘National Storage Battery’ [7,9,10], where it should be added that the first two companies were merged into ‘GS Yuasa Corporation’ in 2004, and that the last one was merged into ‘Panasonic Corporation’ in 2008, as already stated..

3.3 Ni-Cd batteries for Industrial Equipment and Home Appliances

The nickel-cadmium (Ni-Cd) battery, which is a type of rechargeable battery, was originally invented by Waldemar Jungner in Sweden in 1899. Due to its distinctive features of much higher energy density, smaller/lighter property, over-charge/discharge tolerance, higher performance at low temperatures, and longer lifetime property, as compared with those of the lead-acid battery, the demand for Ni-Cd batteries grew dramatically for use not only in industrial equipment but also in consumer electronics [11].

Specifically, in Japan the production of Ni-Cd batteries started in 1953, in order to be substituted for nickel-iron batteries so far utilized mainly for safety lamp in coal mines [7]. Subsequently, Ni-Cd batteries were targeted at standby power supplies installed in electric trains of private/public railway companies, such as Kintetsu’s limited express (see Fig. 10) and JNR’s Tokaido-Shinkansen (Bullet Trains), in the late 1950’s through the mid 1960’s, where batteries were of “pocket type”, constructed of nickel-plated steel pockets containing nickel and cadmium active materials [7,9,10].

In addition, triggered by the Japanese Building Standards Act revised in 1971, which obliged buildings to be provided with emergency lighting, the demand for high-capacity Ni-Cd batteries suddenly increased for use in industrial equipment, such as backup power systems (see Fig. 11), uninterruptible power supplies, disaster-prevention wireless systems, aircraft starting, load adjustment, engine starting for backup turbines, etc.[7,9,10,12]

On the other hand, expecting much of future diffusion of mobile/portable/cordless home appliances, ‘Matsushita Electric Industrial’ acquired in 1962 a USA patent (No. 3,041,388) for manufacturing sintered-plate Ni-Cd batteries [6,10]. However, it was ‘SANYO Electric Co. Ltd.’ that began to release Ni-Cd battery ‘Cadnica‘ in 1964 (see Fig. 12) for the first time in Japan mainly for home appliances [13], where it should be added that ‘SANYO Electric’ was merged into ‘Panasonic Corporation’ in 2011.

Following ‘SANYO Electric’, ‘Matsushita Electric Industrial’ also started the commercialization of Ni-Cd batteries in 1970 (see Fig. 13) [13], which accelerated broadening the application fields of Ni-Cd batteries not only to household products, such as portable/cordless/wireless appliances and electric power tools, but also to miniature button cells installed in photographic equipment, hand-held lamps (flashlight or torch), computer memories, toys, novelties, etc. [6,10,12].
Thus, it can be seen that Ni-Cd batteries also established a firm position in the secondary battery market in the 1970’s [12].

Eventually, as to the historic significance associated with the birth and growth of primary and secondary battery industries in Japan, it can be concluded that ‘Yai Dry Battery Limited Partnership Company’ gave birth to the Japanese dry battery industry, and contributed primarily to its growth, and that ‘GS Yuasa Corporation‘ and ‘Panasonic Corporation’ pioneered a huge market of both primary and secondary batteries installed not only in industrial equipment but also in home appliances, and contributed outstandingly to the advance of battery industries and consumer electronics in Japan.

What obstacles (technical, political, geographic) needed to be overcome?

Japanese primary and secondary battery industries encountered a number of obstacles in the start-up and growth stages, which were timely overcome, as outlined in what follows.

1. Obstacle to Invention of Dry Battery

The obstacle which Sakizo Yai faced before inventing the first dry battery, is briefed as follows: As already stated above, Yai invented in 1885 a battery-powered clock, called the “continuous electric clock”, which was patented in 1891 as the Japan’s first patent related to electricity [4]. Since the battery used in this clock was a wet one with the disadvantage of being unusable in the freeze-up, he began his quest to invent a dry battery, when there was the difficulty that chemicals were leaking out of the positive terminal, and the metal became corroded and unusable.
Thus he worked consistently on impregnating paraffin in a carbon rod, until he overcame the difficulty by finding a sophisticated impregnation method, resulting in the first dry battery invention in Japan [4].

2. Obstacle after Invention of Yai Battery

After Yai invented the first dry battery, there still remained a serious obstacle to the progress of the battery industry. As already stated, at that time ordinary households could not yet enjoy the benefit of electricity even in Tokyo, where candles and oil lamps were still used for light source, and accordingly the demand for battery-powered products was very little.
Against such a sluggish background, the Sino-Japanese War broke out in August 1894, when even the latest Leclanche battery had no use in the Manchuria’s harsh winter cold. Hence Yai got a rush order from the Japanese Army for 50 units of dry batteries, which were successfully utilized for telegraphy in the War [4]. Soon after, an extra edition of newspaper reported the successful achievement of the Yai battery in the Manchuria’s cold, which built recognition of the Yai battery, and consequently made Yai’s company grow to the one with the greatest annual production in Japan [7], as already stated.

3. Obstacle to Manufacturing Lead-Acid Batteries

When Shimadzu established ‘Japan Storage Battery’ in 1917, there was a severe obstacle that the quality of any material used in anode plates was too unstable for their life length to be practically secured. Even though there was an easy choice of importing from abroad the methodology of manufacturing such a high quality material, Shimadzu stuck firm to devising it completely in-house [7].
Through a sequence of trials and errors he at last invented in 1919 an epoch-making manufacturing methodology, called ‘reactive lead oxide production method’, for which he acquired not only a Japanese patent, but also 15 foreign countries’ patents, including French, English, USA, German, and Italian ones [7], as already stated above. Thus Shimadzu contributed outstandingly to the advance of the lead-acid battery industry.

4. Great Kanto Earthquake

Even after Shimadzu invented the revolutionary methodology, there still remained a substantial obstacle to promoting diffusion of lead-acid batteries. It was at that time that the Great Kanto Earthquake struck in 1923, which caused a drastic change in the demand for lead-acid batteries.
Specifically, to cope with urgent request for the infrastructure construction to recover from the Great Earthquake, a tremendous number of lead-acid batteries had to be manufactured for backup power systems installed in factories, office buildings (for example, see Fig. 14), telephone stations, train sheds, electric power substations, etc.

In addition, just after the Great Earthquake, NHK started the radiobroadcast in 1925, which created a sudden demand for dry batteries. Specifically, provoked by the start of radiobroadcast service, numbers of start-ups began to produce specific types of dry batteries dedicatedly for radio receivers, which were, however, supplied mostly by Yai’s company [4]. Furthermore, according as new broadcast stations were opened in prefectural metropolises one after another throughout Japan, a great number of dedicated lead-acid batteries were also put into the market of radio receivers (for example, see Fig. 15; A-type battery for the filament voltage, and B-type for the plate voltage in vacuum tube radio receivers) [7,9].
In this way Japanese primary and secondary battery industries contributed greatly to the post-quake reconstruction.

5. Postwar Reconstruction

The catastrophic destruction all over Japan by numbers of air raids during World War II (1939-45) was the largest-ever obstacle to the progress of the Japanese battery industry. It should be remarked here that just after the War till 1952, GHQ (General Headquarters of the Allied Powers), led by General Douglas MacArthur, enacted widespread military, political, economic, and social reforms in Japan.

In October 1949 GHQ carried out a full-scale deregulation for the automobile production so far restricted rigidly to trucks, resulting in an intense trigger to the motorization in Japan, which increased drastically the demand for automotive lead-acid batteries [7]. In parallel to this motorization, the urgent request for industrial reconstruction all over Japan also expanded extensively the demand for high-capacity lead-acid batteries for use in backup power supplies installed in factories, office buildings, power substations, telephone stations, etc. [7,9,10],.

In addition to lead-acid batteries, nickel-iron batteries were also produced in large quantity in the late 1940’s through the mid 1950’s dedicatedly for safety lamps used in coal mines [7]. Subsequently, in the late 1950’s through the mid 1960’s, triggered by the rapid advance of public/private railroad systems, represented by Tokaido-Shinkansen (Bullet Trains) opened in 1964, the demand for Ni-Cd batteries of pocket type grew suddenly for use in standby power supplies of trains [7,9,10], as already stated.

On the other hand, the drastic progress of carbon-zinc battery business starting in the mid 1950’s, represented by those of Fig. 4, enlarged steadily the postwar market of battery-run appliances, such as lighters for cooking stoves, stove burners, clocks, etc., where it should be added that the annual production volume of ‘Hyper’ grew to 120 million units in 1955 [6]. Thus carbon-zinc dry batteries contributed consistently to enhancing the electrification of Japanese postwar daily life [6,10].

Thus it can be seen that in the late 1940’s through the mid 1960’s Japanese primary and secondary battery industries contributed remarkably not only to the astonishing postwar reconstruction but also to the magnificent diffusion of consumer electronics in Japan.

What features set this work apart from similar achievements?

There are numbers of distinctive features of Japanese primary and secondary battery industries in the start-up and growth stages, which are summarized item for item in what follows.

1. Unique Birth of Japanese Battery Industry

The start-up stage of Japanese primary and secondary battery industries was distinctive in that there were two great figures, Sakizo Yai and Genzo Shimadzu, who contributed primarily to the birth as well as to the growth of Japanese primary and secondary battery industries, respectively, as briefed in what follows.

1.1 Sakizo Yai

Yai was born in Nagaoka, Niigata Prefecture, Japan, in 1863. At the age of 13, he became an apprentice at a watch shop in Tokyo. As already stated, in 1885 he invented a battery-powered clock, for which he attained the Japan’s first patent related to electricity in 1891. Since the battery used in this clock was a wet one with the disadvantage of being unusable in the freeze-up, he began his quest to invent a dry battery. He worked diligently as a hand at a science university laboratory, where he consulted at length with academics on impregnating paraffin in a carbon rod, until he succeeded in devising the first dry battery by finding a sophisticated impregnation method [4,5]. Thus Yai gave birth to the Japanese dry battery industry.
As already stated above, after numbers of troubles and difficulties, Yai’s company managed to release in quick succession numbers of commercially successful batteries of Fig. 2, and grew to reign supreme over the Japanese dry battery market [4]. Thus Yai also contributed to the growth of the Japanese dry battery industry.

1.2 Genzo Shimadzu

Genzo Shimadzu was born in Kyoto in 1869. In 1895 he succeeded in manufacturing the first prototype lead-acid battery. In 1896, only a year after Dr. Roentgen discovered X-rays, he succeeded in producing X-ray images, and moreover, in 1909 he developed the Japan’s first medical X-ray device [14]. Subsequently, in 1917 he established ‘Japan Storage Battery Co., Ltd.’
As already stated, this new company faced a great difficulty that the quality of any material used in anode plates was too unstable for practical use. After a great deal of trial and error Shimadzu invented in 1919 a revolutionary methodology, called ‘reactive lead oxide production method’, for which he acquired not only a Japanese patent but also 15 foreign countries’ patents [7].
Thus, it can be seen that Shimadzu contributed outstandingly to the birth and growth of the Japanese lead-acid battery industry.

2. Contribution to Postwar Reconstruction

As already stated, in 1949 GHQ implemented a new law of deregulating the automobile production in Japan so far restricted strictly to trucks, which served as an intense trigger to Japanese motorization, and therefore created a drastic demand for automotive lead-acid batteries. In parallel to this motorization, upon urgent request for the postwar reconstruction all over Japan, the demand for high-capacity lead-acid batteries grew dramatically for backup power supplies installed in factories, office buildings, power substations, telephone stations, etc. [7,9,10].
On the other hand, in the late 1940’s through the mid 1950’s, a great amount of nickel-iron batteries were also produced mainly for safety lamps used in coal mines, which contributed greatly to the postwar mining industry [7], as stated before.
Thus it can be seen that the secondary battery industry, led primarily by ‘GS Yuasa Corporation’ and ‘Panasonic Corporation’, contributed enormously to the postwar reconstruction all over Japan as well as the motorization in Japan.

3. Contribution to Consumer Electronics

As already stated, ‘Matsushita Electric Industries’ together with ‘SANYO Electric’ released a tremendous amount of carbon-zinc, silver-oxide, alkaline-manganese, Ni-Cd, and lithium batteries in quick succession in the mid 1950’s through the early 1970’s, with which a huge market of consumer electronics was created in Japan, where it should be noticed that
(i) carbon-zinc batteries, represented by ‘Hyper’, ‘Hi-Top’, and ‘Neo Hi-Top’ of Fig. 4, expanded drastically their application fields in consumer electronics [6], with the greatest share of the total production volume of primary batteries in Japan [12],
(ii) alkaline-manganese batteries broadened their applications to newly introduced appliances, such as tape-recorders, 8-mm movie cameras, strobes, shavers, etc., due to strong load performance and low- temperature characteristics [6,12],
(iii) Ni-Cd batteries contributed greatly to expanding their applications not only to new consumer products, such as portable electronics, cordless/wireless appliances, electric power tools, etc., but also to miniature button cells installed in photographic equipment, flashlight/torch lamps, computer memory, toys, novelties, etc.[6,10,12],
(iv) lithium batteries released first in 1971 contributed extensively to the widespread diffusion of today’s digital appliances, such as digital watches, personal computers, digital cameras, mobile terminal devices, etc. [6,12,13], and
(v) ‘Matsushita Electric Industrial Co. Ltd.’ together with all of its subsidiaries and ‘SANYO Electric’ have been merged into ‘Panasonic Corporation’, as already stated.
Thus it can be seen that ‘Panasonic Corporation’ contributed distinctively to creating a huge market of primary and secondary batteries for use in consumer electronics.

4. Overseas Expansion

After World War II, Japan resumed the international trade, firstly working on the export of automotive lead-acid batteries to South East Asia, Middle East, Africa, South America, and USA, among which South East Asia became the largest market in the 1950’s [7]. Accordingly the Japanese auto industry started car exports to South East Asia in the early 1960’s, where on-site car assemblies were also undertaken. In step with this business trend, the big three battery companies, ‘Japan Storage Battery’, ‘Matsushita Electric Industrial’, and ‘Yuasa Storage Battery’ established joint business ventures for manufacturing automotive batteries in the late 1960’s through the mid 1970’s in South East Asian countries, such as Thailand, Indonesia, Sri Lanka, Singapore, Malaysia, etc. [7,9,10]

On the other hand, as for the dry battery business, ‘Matsushita Electric Industries’ established joint business ventures for manufacturing dry batteries in the early 1960’s through the early 1970’s, not only in Asian countries, such as Thailand, Malaysia, Taiwan, India, Indonesia, and Philippines, but also in South American countries, such as Peru, Costa Rica, and Brazil [6].
Thus it can be seen that ‘Panasonic Corporation’ and ‘GS Yuasa Corporation’ contributed extensively to the progress of both primary and secondary battery industries in Asia and South America in the early 1960’s through the mid 1970’s [6,7,9,10].
